Initialization of Main() in java and seeking alternative code

Question

I am given a following partial Java code:

public static void main(String[] args) {
  var main = new Main();
  main.start();
}

I don't understand the initializing in Line 2 (Main()).

Also, what is the datatype of Main()? Suppose, I don't want to use 'var' keyword, then what should I use?

If there is any alternative code for this, please let me know.

Answer 1

I don't understand the initializing in Line 2 (Main())

You're initializing an object of type Main, in order to call the instance method start()

The alternative is to replace var with Main

Or simply new Main().start();
